Some vendors' implementation of barrel-type power connectors were fragile - or rather, they weren't but placed a bending moment on the laptop's board and breaking it.
The USB C socket on my phone has been used multiple times a day (more plug / unplug cycles than I would expect a laptop to endure) for years now, without issue.
I haven't seen any evidence that USB C sockets result in less durable kit. When next buying a laptop, I personally though would prefer a machine with at least two USB C sockets and that be charged from either.
If you're really worried, you might investigate USB C magnetic breakaway connectors (though do check they're rated to USB C PD specs)
